SHODDY-PURIFIER.

SPECIFICATION forming part of Letters Patent No. 334,776, dated January .26, 18$ 6. Application filed December 1,1863. Renewed Julyil, 1885. SerialXo. 170,642. (No model.)

To all whom it may concern: apartment and extending from wall to wall of Be it known that I, EDWIN M.

the cylinder may be free of either spikes or spiral flange. -In this event, however, it is apprehended the shoddy will not be as thoroughly agitated and cleansed.

There are many changes which may suggest themselves in the matter of design and con struction; but these, if they do not accomplish a departure from the spirit of my invention, I consider as immaterial.

What I claim as new, and by Letters Patent, is-

1. The combination, with the revolving cylinder D, perforated shell D, surrounding the same, and the exit-pipe E, of the blast-pipe e, supplying picked rags between said cylinder and perforated shell, all arranged substantially as herein set forth.

desire to secure 2. In a shoddy-purifying machine, the combination of arevolving cylinder having spikes, a perforated shell surrounding the same, a blast-pipe supplying picked rags between said cylinder and perforated shell, an exit-pipe leading from the space between v the cylinder and shell opposite to the end where said blast enters, and a dust-chamber having suitable outlets, in which the whole is placed.

In testimony that I claim the foregoing as my own I have hereunto affiXed my signature in presence of two witnesses.

EDWIN M. HULSE.
